V VEHICLE SPRING SUSPENSION.

1,1312%. Specification of Letters Patent. ramm d M 9, 19 115 Applicationfiled August 26, 1914. Serial No. 858,726.

following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains'tomake and use the same, reference being had to the accompanying draw.ings, and to the letters and figures of reference marked thereon, whichform a part of th s specification.

This invention relates to new and useful improvements in vehicle springsfor use in overcoming the shock from uneven roads and preventing theswaying ofthe body portion of the vehicle and comprises a simple andefficient apparatus of this nature having various details ofconstruction, combinations and arrangements of parts which will behereinafter fully described, 'shown in the accompanying drawingsand thenspecifically defined in the appended claims.

I illustrate my invention in the accom panying drawings, in which:

Figure .l is a rear elevation of a vehicleshowing the application of mysprings there to. Fig. 2 is a sectional view on line 2-2 of Fig. 1, andFig. 3 is a sectional view on line 3-3 of Fig. l. l

Reference now being had to the details of the drawings by letter, I Adesignates the body of a vehicle, B the axle and C the hub flanges, eachof which fits over the axle and each is provided with two upwardlyprojecting wings I), spaced apart, which are a ertured for the receptionof a bolt E. up porting springs l are pivotally connected at their lowerends to the bolt E and their upper ends are connected with the links Hand which are fastened to the inner endsof the springs I, the outer endsof said springs being fastened to the plate K secured to the body 0f thevehicle.

The body of the vehicle is supported upon springs N which, at theirlower ends, are fastened in the apertures .l in the stump "shapedmembers J, a detail of one of which is shown in Fig. 2 of the drawings.Said members J lit over the springs F and are held in place by means ofthe plate F through which bolts 1 pass.

Itwill be noted upon reference to the are drawings that the springs Fare positioned directly above the axle while the springs N 1 positlonedone upon either side of the ax e.

By the provisionof shock absorbing means made in accordance with myinvention, the'vibration incident to a vehicle passlng over rough roadswill not come directly upon the body springs N, but rather upon thesprings F at the lower ends thereof, the vibration being minimized ortaken up by means of the coiled springs I. By the arrangement of theSprings 1 as shown, it will be noted that a direct pull is affordedagainst any swaying motion of the body of the vehicle. The connectionbetween the springs l and the bolt upon the wings may be positionedagainst the hub, reducing the strain upon the axle to minimum. By thearrangement of the springs shown, the

heavier the load the more direct will the pressure be thrown into thehub, thus reliev ing the center of the axle of vertical s rain.

What I claim to be new is L-An apparatus for taking up vibrations andpreventing swaying of vehicle bodies,

comprising, in combination with an axle and body of the vehicle,projections upon the axle, leaf springs connected to said projections,hangers pivotally mounted one upon each leaf spring and having aperturedends, resilient connections between the upper ends of the leaf springsand the side walls of the body of the vehicle, springs secured to thebottom of the body and supported at their ends upon said hangers.

2. An apparatus for taking up vibrations comprising, in combination withan axle and body of the vehicle, projections upon thexaxle, leaf springsconnected to said projections, a hanger pivotally mounted upon saidsprings and having aperturcd ends positioned one upon each side of thearle, springs secured to the body of the vehicle, one upon either sideof the axle and engaging an apertured end of the hanger.

3. An apparatus for taking up vibrations and preventing the swaying ofvehicle bodies, comprising in combination with an axle and body of avehicle, hub flanges upon the axle, leaf springs having their lowerouter and preventing swaying of vehicle bodies, I

ends connected to said hub flanges, staplethe leaf springs with theopposite sides of In testimony whereof I hereunto affix my the body ofthe vehicle, and supporting signature in presence of two witnesses.
